- Nov 3: The way podcasts are being measured in France has changed, reports La Lettre Pro. Shows previously measured directly by Médiamétrie are now being measured by ACPM, in data that is apparently “compliant with IAB Tech Lab standards” (though ACPM isn’t certified). Médiamétrie used to use a redirect system (like Podtrac or OP3); this new system, coined “EAR > Podcast”, uses logfile analysis (like Triton’s rankers). The #1 show in the September EAR > Podcast ranker is RTL’s Les Grosses Têtes; Médiamétrie’s clients are mostly radio companies, and this ranker measures participating publishers only. ACPM’s own ranker continues; #1 in that is Acast’s HugoDécrypte.
- Oct 8: Podtrac released the September 2025 US rankings for publishers and podcasts. In the podcast ranking, The Charlie Kirk Show saw a rise from #34 to #6 (his fatal shooting was on Sep 10); SiriusXM’s Fantasy Footballers moved from #34 to #9 (the new NFL season kicked off on Sep 5); and Morbid jumped from #404 up to #11 (this is essentially “the highest new entry”, given the show shifted to SiriusXM on Sep 1 from Wondery, which isn’t a participating publisher). As ever, these rankers measure participating podcasters only.
- Sep 8: Podtrac also released its rankers for August 2025. Most publishers saw an increase in audience. Wondery isn’t a participating publisher.
- Sep 2: Livewire has published its graphs and data for the industry for August. There are no major changes for “podcast hosts by episode share”, though Libsyn has hit a low of 3% for the first time. For tracking services, Podtrac now measures a record 14.3% of all new episodes.
- Aug 29: Of note: the article (part of a “News Literacy Edition”) claims that NPR is the third-largest publisher in the US, citing Podtrac. Podtrac, though, measures participating publishers only.
